Dlux Berg Build
 

Moving into the MOA world...

Looks like I have about a week before I get the rest of my parts for this car so I decided I will do a build thread while waiting. I have found the most challenging part of building this car is the availability of parts. It seems like everything is back ordered or just not offered anymore.

One of the things that has always held me back from the MOA cars is the extra weight. Ironically I believe this car is going to weigh less than my Losi. I still do not like the weight of the motor being on the back axle and I am being conscious of weight overall so I am paying extra attention to where I am putting the weight and how much everything weighs. Ideally I would like zero weight except for knuckle weights.

The best part of starting off with a relatively heavy car is that you have so many options of where to take weight off.

I was really surprised what a little grinding and shaving on the gear case could do.

Next were the gears.

I dont have my mill yet so I could not mill them. I didnt want to drill them because usually when you drill small parts like this and try to be precise it looks like crap. So, I turned my on the lathe. I really like the way they turned out.

Stock 2nd 13g

Good luck with the build. I think you'll dig the moa over the Losi "thumbsup"

I'm having the same problem with my build, started from scratch. I guess
that's one down side. Parts won't be made forever.

Then the 4th gear and locker. Youre a fool if youre not running the RCbros locker. They weigh much less and are cheap to boot.

A couple holes later... 7g

Then I moved on to the axle tubes. There were a couple of things I wanted out of the axle tubes that I could not find.

• Ultra light weight
• Clearance for 86Jeep style steering with out modifying the tubes
• Not having to mess with clocking every time I want to change my caster
• Have the ability to clock my shocks/links
• Smaller inner diameter axle tubes so that the rear axle shafts do not have the opportunity to bend within the axle tubes

Since I could not find all the above that is on the market I set out to make my own. These are just the prototypes and I need to run them for awhile but if all goes well they should be on the market soon. I have figured out recently that I need to up my game a bit to be competitive. So, the best part about these is that they are all made in house. This will keep my prices lower and I wont have to deal with stocking issues.

Good to see you switching over too... Good luck on the build "thumbsup"

Very cool stuff! "thumbsup"

I put it all back together with some DLUX chromo gear pins and wheel pins, Mann 2nd and 3rd gears.

When I started dealing with the knuckles/C's I had a hard time believing you guys deal with the amount of slop that these cars have in the king pins so, I had some no slop king pin bushings made.

Edit:
Important note:
The bushings are made to work with the stock stainless steel screws. If you use a different brand stainless screw, aluminum screw, steel screw etc,. you may find some will not even fit or be sloppy. After measuring many brands and different materials I have found the screws to vary greatly. I have not found a steel screw or aluminum screw that will fit.

And,... this is where I am at now. I have the axles complete and am working on shock mounts and a servo mount. I just got some new tools to help me along with all of this. It has been keeping me real busy setting the tools up and doing a crash course on some lite CAD to build some of this. I hope to be able to offer the servo mount and titanium tie rods for either Berg style or Axial style when I get everything together so I can offer somewhat of a complete kit that will get everybody everything they need axle wise.

DLUX front axle thus far 8.2oz

http://i180.photobucket.com/albums/x...g/100_1688.jpg

DLUX rear axle thus far 7.2oz

http://i180.photobucket.com/albums/x...g/100_1705.jpg

Stock axles total 21.4oz, DLUX 15.4oz.

The above rear axle is with 6mm rear shafts. If I would have kept the stock dog bones in it would have reduced another .14oz coming real close to 7oz total.

Oh, forgot to add...

I am super stoked. I was worried that there was no way I would be able to keep my 7980 servo and the 86jeep steering. With the small diameter axle tube I am able to keep it if I run a 14t pinion. A smaller servo such as a 7950 fits with just moving the motor up on the case and a 12t pinion (or smaller if you want) this is with zero mods to my axle tube.

Thanks guys. I am pretty excited to work on some new stuff.

Have plans on producing more axle tubes? :shock:

Edit: missed some stuff when reading early this morning. Exciting info here. Can't wait to see
what comes available after some testing.

First off...I know what you mean about waiting on parts and most of them being out of stock...it's aggravating, but part of the game at this point. Your parts are looking good and I'm looking forward to seeing what you come up with for link mounts.

I believe he is saying that he will "thumbsup" It actually sounds like we'll be seeing the availability of quite a few of the parts needed to make D lux Berg Axles in the near future!

Looking good Erik! I'll be watching this progress :mrgreen:

Very cool! I like those tubes!

Oh man, all that white delrin! I need to stay out of the berg section, all the cool kids are switching over, I can't abandon my XR....


Nice work Erik, this is gonna be an impressive build.

Proper!

Yep. Just need to do some testing.

As soon as I get the car together I will be able to put some serious time on it now that its summer.

Yeah. Its super frustrating. What would be even more frustrating is if all these great parts did not exist. This hobby is cool because its made up of a bunch of regular guys that produce great parts, many in their spare time. This is much easier to see when youre on the vendor side and not the waiting customer side though :lmao:

Thanks!

Thanks

Thanks

I am not sure if the white will be a one off/limited version or not. I think I am one of the only guys who like white and it is much harder to machine and keep looking clean. I do think it looks better after having to deal with some abuse though. Most likely the majority will be black. I cant remember where I read it but I have heard there is a strength difference from white to black? I am also curios what the strength difference would be between the colors in the sun. When I first got my temp gun to monitor my motor temps on my Losi I checked the temperature of everything around me in mid summer. Anything with any color added to it was 160*+ anything white based was 120*.

Thanks

I edited the post on page 1 with the bushings but wanted to add it here too in case it was missed.

It's great to see more New products being developed for the Berg's Erik "thumbsup"
I'm looking forward to seeing what else you have planned .

Subscribed .

dang that thing looks amazing :)

Sorry. This morning I was like a child, looking at the pretty pics but not reading
everything. Excited to see what ya come up with "thumbsup"

I'm excited to see what you do with the upper link mount and steering link. The tubes look kick ass!

Your off to a great start, can't wait to see what else you come up with"thumbsup"

Kieren

Looks sick man can't wait to see all the new parts to come"thumbsup"

looking awesome there Eric. Having a few bits from you already, know that anything you put out into the market will have great build quality and will be duable.

Looking forward to seeing the link/shock mounts. The delrin rear tubes I have on my Bully are great, they've stood up well to the beating they've taken the thought of some good delrin rears for the Berg to ooooooooooh yeah 8)

Defo a subscribed thread "thumbsup"

"White" or natural is Delrin's normal color, meaning no additives are used to changes its color. Black they add in concentrated colors to produce, sadly this can negatively impact the overall material properties because Black Delrin doesn't exist, so they add in other chemicals/plastics to Delrin to make the color change.

White is a better choice IMO due to unchanged material properties.

Very true, we often forget the time/money involved for the great vendors to help us out.

Look forward to the rest of the build, and hope we see some cool new parts available due to this build! "thumbsup"

Reflection vs. Absorption of heat/sunlight."thumbsup"

Wow!
I am glad to see you coming to the dark side!!!

I have no doubt that this will be one sick rig!!!

I am interested to see how the delrin tubes work.
I had quite a few people ask me for them last year when we were working on bully tubes.

You going to have it done for the next comp??

Nice work Erik "thumbsup" .... but ......
















it will never be a Losi :mrgreen:

Looking Sweet Erik! Keep up the great work and hope that testing works out:) Nice to see guys willing to bring it and test it

maybe come up with your own rear chromo rear axles as well"thumbsup"

You could shave a little more off the tran case for a few more g's"thumbsup"

Pretty sure the fact that this will never be a losi is the point of this build....lol
I have been trying to get Erik out for some fun crawling for like 2weeks he tells me he would rather not Even drive if he has to drive that losi for another day!! Lol





The build is looking great Erik...hope that rockshow ss shows up soon so we can get out and crawl!!



Btw I vote for black delrin tubes...hehe
